The problem is that so many people here did not get to experience end game content before Wraith so ofc Lich king is going to win.

Personally Kil'jaden was amazing and the lore in the fight and the entire build up was just great, but I think like 2% of the player base during BC even got to Kil'jaden let alone the playerbase now, it is probably .02% fought kil'jaden in BC

To me it had to be the Lich King i mean he was front and center in many of the quest and zones in wrath. Unlike in BC you were not just seeing the bad guys forces at work as you leveled and quested you got to see your end goal. People have their issues with Wrath but to me the story in Wrath was done the best out of all the xpacs so far. I first got into warcraft when i played warcraft 3 and when i heard WoW was coming out and undead were a race i was like "Sweet i can fight for the lich king" tho of-course as i found out it was the forsaken i was a little let down but i knew someday we would get to take a trip to Northrend to deal with him. Even threw a good portion of vanilla you were haveing the eventual showdown built up with all the end game questing in the WPL and EPL ending of course with Naxx.

the others idk KJ was never mentioned enough in BC and you never really felt his presence til sunwell so much so alot of people thought illidan was the end boss in BC for a long while. Deathwing and Rag while shown and their presence felt i just didnt feel the story was as well done. As for MoP i think the story leading up to the siege or org has been really good idk i still would place it behind the Lich King but i have to wait and see how 5.4 unfolds.

What the fuck, where's Illidan? I would put Kil'jaeden in 2nd, just because it was such an awesome sight to behold, but I'm refusing to vote for this glaring oversight. Illidan almost made me cry when I saw him the first time.

I think this poll should just be scrapped and started over properly because I'd really like to see people's opinions of Illidan vs LK. On the other hand, a whole hell of a lot more people probably managed to fight LK while he was current than Illidan, because of the higher playerbase, 10-man raids, and the stacking buff mechanic. (Which is why I think BT should be brought back Naxx style in a future expansion, not enough people got to see it in all its glory imo.)

Also if the poll is including mid-tier end bosses like Sha it should probably include Kael'thas, a hugely important lore figure from BC and one of the most epic, well-designed and memorable raid fights in the game. (Vashj and Archimonde were cool fights in their way but easily overshadowed by KT, plus Vashj's storyline in particular was... not so nefarious. I'm taking over Outland's water supply! I r so evil!)

Your option for vanilla being rag is confusing to me. He was t1 boss. Lore wise extremely poor. Nef had much more lore surrounding him and C'thun was off the charts epic wise for a fight. Then you had the lore bomb and awesome KT fight in naxx 40. Sadly they derailed that story and went to outlands with TBC killing the KT fight. Yogg Sauron also was a more epic and lore filled fight to me than LK. However LK gets all the Warcraft 3 players in a frenzy because it closed that chapter for good.

Since he isn't on the list my .02 would be C'thun. Everything that went into AQ 40 made that place AWESOME. From the gates opening to the fight itself and all the lore around our first encounter with an old god.

Classic Ragnaros.
We had people kicked out of the guild for talking during the event.

no boss ever again managed to do that.

plus he was more frightening than any other boss. you stood there with what? 1k life as a dd in more or less only blues? doing like 120 dps. AND THIS DUDE WAS THE FIRST DUDE WITH A HEALTH WITH SEVEN DIGITS.

For sure not the LK we saw in Wrath. Anti-climatic and bad storyline overall.
I'd say Yogg-Saron, real masterpiece of that expansion, along with Vanilla Ragnaros and Illidan (not KJ) in TBC.
Deathwing was really epic visually, but the fight missed something.

Vanilla Rag had two zones and a dungeon devoted to telling his story, beyond the actual raid, plus all the quests that involved the Dark Irons. The fact that the mere act of summoning him caused the middle third of the continent to explode made for a tense lead-up to his fight. Being that he was the tier 1 boss, the devs were able to basically build his story into the world, and it showed. I can understand him being in the list.

The fight sucked, but the lore surrounding him is epic in the purest sense. The fact all the Dragon Aspects are involved in the fight alone is huge, with the end of the world literally hanging in the balance.

People talking about specific difficulty, % of playerbase doing the content, etc. do not seem to realize that there is "lore wise" in the question. We are talking about a story character, not a raid boss. The raid encounter itself is just a small part of that boss epicness. Hell, one doesn't even have to kill the boss at all and can still make a valid point in this poll.

The Lich King, by far. As someone who's been into Warcraft since before WoW (having played Reign of Chaos and Frozen Throne campaigns) and following Arthas since he was still a paladin, I'd been waiting a long time for the closure that came with Wrath of the Lich King. Plus...some of the Lich King cinematics were by far the best in WoW, in my opinion. I got some chills the first time I watched the opening Wrath cinematic. That was truly epic.

TBC was my favorite overall expansion, but Wrath had my favorite end boss.

If you had played WC3, you would know were CoS came from, there is nothing wrong with it, i even think it was one of their best 5 man instances they ever maded.

Actually, I did play Warcraft 3 and thats why I don't like that dungeon. In Warcraft 3, it was an emotional moment, a very important part of Arthas' journey.

But this did not work that well when converted into playable MMO content. Cheesy dialogues, Arthas' human model, game mechanics requiring him to hit citizens one-by-one as if they were target dummies, whole Infinite dragonflight felt out of the place (more vile sorcery!), bronze drake becoming a synonym for average LFD mouth breathers, unskippable intro day after day when farming ... should I go on?

I wanted to say that sometimes, the way they told the story did not quite work out, even when what were they telling was interesting.
